NextGen™ Dynamic Message Signs / Variable Message Signs

NextGen™ is top of the class, eco-friendly and low power dynamic message signs (variable message signs) technology that does not require periodical maintenance, manufactured by Telegra, one of the world's leading innovators and manufacturers of dynamic message signs (variable message signs) technology:

Reduces cost of ownership up to 60% during lifetime,

Its building block is a waterproof (hermetically sealed) module – casing for all electronics and optics,

Eliminates all major functional and mechanical problems of traditional signs,

Suitable even for extreme environments (temperature -40 to +164°F, humidity 0-100%, AASHTO wind extremes, vibrations, ice, snow, freezing rain, blowing sand) High reliability in all conditions with MTBF over 40,000 hours and availability greater than 99.99% - automotive industry technologies, redundancy of important components, minimized number of mechanical contacts Completely under your control – advanced diagnostics of all Dynamic Message Signs functionalities at any point in time - includes the status of each component, cold state LED testing, usage statistics of aging elements (fans, LED, etc.) Ultimate optical performance - exceeding the highest optical classes according to NEMA TS-4 and EN12966

Total Flexibility

Customizable as any other application-tailored display (size, pitch, optical properties, consumption, service access, redundancy requirements, set of standardized accessories) Any application, any size, any interface, and any housing execution (front & rear access, walk-in) - over 150 different models available Connectable to any existing system - certified and proven compliance with most widely used protocols (NTCIP, TCP/IP, PROFIBUS, MODBUS, XML-OPC, etc.); customization to any user protocol (numerous examples of implemented projects)

Traffic Safety

Outstanding display recognizable within 1 second - Telegra’s unique certified lens system provides distinctively clear, recognizable, uniform messages, easy to read from distances within 55 to 430 yards Smart intensity control – controlling the luminance intensity in 100 unit increments, based on outside illumination, provides optimum light output to the driver, which enables the best legibility No limits to information transfer - any true type font, in any formatting style, in any language, combined with any predefined bitmap, in any color, in one single message Smart fail-safe operation - performs constant self-testing and evaluates if message is recognizable - only correct message will be sent to the sign

Walk-in signs are considered as a standard for today’s most prestigious LED traffic displays. The decisive competitive advantage for choosing this solution is traffic safety during the Dynamic Message Signs maintenance procedure (nothing can fall down on the road during maintenance procedure). Additionally it brings reduced maintenance cost as there is no need for road closure during maintenance.

Classic Execution Dynamic Message Signs (Variable Message Signs)

Our capability to customize any desired execution, dimension and matrix combination resulted so far with more than 300 different models of Dynamic Message Signs delivered to 35 countries worldwide in more than 10,000 units. Weather they are small lane use signs, speed limit or any other symbol, matrix, color, dimension or pixel pitch, they all share same differentiating features of Telegra’s Signs of Intelligence technology:

Telegra Quality Assurance and Quality Control Process

Thoroughly tested technology:

EN12966 certification – initial type testing of a test-module, consisting of the same devices and properties as a real sign (a true representative of the technology). The test-module is built of the same materials, using the same coating and corrosion protection, and the same electrically and electronically devices as the real sign. The front-display shows areas equipped with light emitting elements (e.g. LEDs) of the colours, light sources, element spacing (i.e. pixel pitch) used in the real signs:

Following table gives examples of tests in initial type testing:

Durability and accelerated aging tests (simulation of 10 year aging) of all the components and fabrication procedures that are exposed to environmental influence

Seal under the test:

Samples in weather-o-meter test:

Certified and annually controlled production and quality control process

Annual factory production control of Notified Body according to EN12966 – Part 3

Annual quality system control and recertification according to ISO 9001:2000 by TUV

AASHTO and EN12899 calculation and simulation of each model Structural performance of each model of a sign is verified either through AASHTO applicable calculation and simulation or EN12899 applicable calculation and simulation. If required, calculation results are presented to client or responsible engineer.

Only selected, verified and tested componentsComponents used for fabrication of modules and sign frames are all carefully chosen, type tested in EN12966 and accelerated aging tests, and long-term tested in Telegra to assure Telegra quality. The tests include:

EN12966 certification – initial type testing procedures

Durability and accelerated aging tests (simulation of 10 year aging) of all the components and fabrication procedures that are exposed to environmental influence

Accelerated aging tests of LED's in Telegra lab

Quality control of each purchased batch of the components – functional control and traceability recording

Special production machines to assure highest precision of fabrication

custom-made production tools for each segment of the module – assures precision and optimum fabrication conditions for each component

special front face coating application machine

special sealant application machine

special gauge for water immersion tests

high-stress temperature testing chambers

burn-in testing polygons

Environmental tests performed on each manufactured module

High stress temperature changing from low to high extremes (-40 to +85 degrees)

Water immersion test of each module to prove IP67 protection

Optical tests of each batch

One piece from each manufactured batch of each model of a sign is tested in Telegra's optical lab for full optical performance according to EN12966 declared classification – luminance, beam width and reflection ratio

Functional and burn-in testingAfter assembly, each sign is being functionally and burn-in tested. During long-term burn-in integration testing all delivered signs are tested in minimum 168h period while status of devices is monitored 24/7. Long term testing is extremely important for devices that must operate 24/7 on distant locations, where maintenance is expensive. Long-term burn-in testing assures that more than 90% of expected faults (that usually occur in first days and weeks and operation) are solved in the factory, prior to delivery.
